Application filed January 27, 1927, Serial No. 163,916, and in GermanyFebruary 12, 1926.

vOur invention relates to storage reservoirs for gas and the like, ofthe class-commonly referred to as waterless gas reservoirs, in which, inprictice, the sealing function is performed by a sealing disc verticallymovable in the gas reservo-ir in accordance with variations in -the gascontents thereof. Such reservoirs generally consist of an upright shellof cylindrical or polygonal form, built up of plates arranged in courseson vertically arranged stationary posts. in reservoirs of this type itis of advantage to utilize the vertically movable sealing disc as anadjustable interior working scaffold to facilitate the erection of thereservoir and to progressively raise the roof structurethereof to itsfinal position. Under such conditions, the sealing disc is periodicallyraised to a predetermined extent to keep pace with the upwardconstruction of the reservoir. ln order that eX- ternal work may be doneupon the shell as its erection proceeds, it has heretofore beennecessary to erect a special scaffolding and framework eXtei-iorly ofthe shell. The ob- `ject ofthe present invention is to avoid thenecessity for such specially constructed scaffolding, which of necessitymust be progressively increased in height as the erection proceeds, andto provide a scaffold framework and erecting platforms carried by theaforesaid dise and partaking of the progressive upward vrmovementsthereof and requiring no structural changes or additions during theperiod of` erection. Other more specific ob-. jects will appear from thedescription here-l inafter andthe features of novelty. willbe pointedout'` inthe claims.

Reference is to be had to the accompanying drawings which illustrate anexample of the rinvention without defining its limits, andv in whichFig., 1 is a fragmentary sectional elevation'showing the inventionapplied to a v gas reservoir in the process of construction; Fig.l Qisan enlarged fragmentary section; and'Fig, Sisafview similar to Fig.` 2,illustrating the inal stages in theerection of the reservoir.

In the drawings, a represents the customary upright' posts which formpart of the reservoir andupon which the metallic plates, constitutingthe shell o, are fastened in contiguous courses to complete thestructure. The sealing disc c may be of any conventional constructionwhereby the interior of the reservoir is sealed, and in the well-knownway is provided with rollers c adapted to v travel lengthwise of theupright posts a to y facilitate the raising and lowering. ofthe disc. nAs shown in the drawings, the roof structure (l is temporarily supportedupon the 'disc c by means of supports al on which supportinghooks eare-pivoted-for Vengagement with projections extending. inwardly fromthe upright posts a; it will be understood that these'projections f areshifted along the posts a and secured in new'positions in anyconventional way to keep pace with the eiection of the shell Y).Suspending mem-v bers 7L project outwardly from a suitable portion ofthe disc c and are secured in place in lany convenient manner, saidsuspending members extending outwardly beyond the peripheral boundary ofvthe reservoir, as clearly shown in Figs. l and?J of the drawings. lnorder to provide the desired rigidity in the construction, stays z/ mayextend from the suspending members 7L tothe i'oof structure d, asillustrated, for. instance, in

Fig. 1. A scaffold framework h2 depends from the suspending member-shIand is secured'thereto in any convenient waysaid scaold framework beingof such lengthas "to depend downwardly beyond the advanced oruppermostline of erection into contiguity to previously erected portions of thestructure, in external relation to the reservoir. In the illustratedarrangement, an upper platform (j and a lower platform g" are carried bythe scaffold framework 71,2 and are supported thereon for instance bymeans of crossbars c' and e" respectively. In the preferred arrangement,the'pl-atforms g and g are mounted upon the scaffold frameworkso as tobe capable of being moved to positions to avoid obstructions suoli asgalleries m projectingoutwardly from theI reservoirf and tending tootherwise interfere-.withlthe upward travel of said scaffold'frameworkand its platforms. ln the illustrated arrangement the crossbars and fare accordingly pivoted at -c and k i'espectivelyto thescaffold-framework la?, itbeing understoodthat suitable means isprovidedfor lockingsaid platforms against unintentional movement on theframework; for the purpose yof facilitating the pivotal movements ofsaid platforms-the crossbars z' and may be extended outwardly beyond thepivots 7c and lo for the.

accommodation of counterweights Z and Z', which serve to assist inswinging said platforms to inoperative positions when this may bedesired. In Fig. 2, the platforms g and g are shown in dotted lines inan intermediate position during their movement from the position shownin full lines on said figure to the vertical position in which they willclear the obstruction m. rlhe arrangement is such that the platforms gand g extend circumferentially of the reservoir in external relationthereto and at such a vertical distance apart that as the upper platformis used by workmen for advancing upwardly the courses of plates o uponthe posts a, the

lower platform g may be coincidentally use-d by workmen carrying onfinishing operations, such as riveting of the plates in place.

In practice, the lower courses of plates b are placed in position insuperimposed courses to provide an enclosed shell built up to a heightconveniently accessible to the workmen without the assistance of anyspecial apparatus. At the 'proper time the disc o is placed in positionin the completed part of the shell, and the roof structure d issupported in place thereon as shown in the drawings. The disc c, withthe roof structure CZ in place thereon, is then raised by means of airpressure from below, or in any other suitable manner, to the levelindicated, for instance,A vin Fig. l, at which level the 4disc and theroof structure are positively supported by means of the supporting hookse and the projections f, which have previously been placed in position.Either at this time or at some previous time, the scaffold framework h2and the platforms g and g are combined with the disc c V and with theroof structure d, as illustrated.

As the upward erection of the shell now proceeds, the disc c isperiodically raised to progressively higher levels, at cach of which itis positively supported throughthe medium of the supporting hooks e andthe projections f, the latter being ,re-located along the posts a asnecessary. The scaold framework 71,2'

and the platforms g and g partake of the upward movements of the disc candthe roof structure d, and thus provide working platforms, located inexterior relation to the reservoir, whereby the erection of the shellmay be carried on with a minimum of effort and the riveting thereof inplace may be elliciently carried on.

Then the disc has been raised to such a height as to bring the roofstructure d to its final position, the latter may be secured in place inthe conventional way. In this upl permost position ofthe disc, thescaffolding framework and its platforms g and g have also reached anuppermost position, determined by the location of the roof structure inits final position.l Due to the fact that the Vroof structure is at adistance above the disc c and that the latter is no longer available forraising the platforms g and g beyond the point determined by the finalposition of the roof structure, the platforms g and g at this time arelocated at a distance below the uppermost point to which the shell is tobe erected. In order that said platforms may be utilized for thecomplete erection of the shell, pulley blocks o are suspended frombrackets a which project outwardly from the roof structure beyond theperipheral limits of the reservoir, as shown in Fig. 3. The pulleyblocks o accommodate cables g, each having one end secured, forinstance, to the upper platform g, and its other end fastened to winch pso as to be capable of being wound up on the same; the Winches p arefastened in place in any suitable manner upon the upper platform g. Thesuspending members t and the braces L are now removed, so that at thisstage the scaffold framework and the platforms are suspendedfrom thebrackets n by means of the cables g. By suitable operation of theWinches p, either manually or mechanically, the cables Q may be wound upon said Winches to thereby lift the platforms g2 and g to whateverextent and in such progression as may be desired.

The arrangement provides a simple and convenient construction includingworkmens platforms located exterlorly of the reservoir andautomaticallyraised in progressive stepsl l spirit of our invention.
